BAYER-FILING PUNCH.

Application filed April is,

1 My invention relates to a means for preparing papers, such as letters and similar documerits, for storage by filing them in a group.

An object ofmy invention is toprovide means for neatly arranging a plurality of pa: pers and perforating them for the reception of a fastener.

Another object of my invention is to provide a filing punch which can conveniently be held in the hand of the user- Another object of my invention is to provide a filing punch which can advantageously be made from a single sheet of material.

My invention possesses other advantageous features, some of which with the foregoing,

will be set forth at length in the following description where I shall outline in full that form of the paper filingpunch of my invention, which I have selected forillustration in the drawings accompanying and forming part of the present specification. In said drawings I have shown one form of paper filing punch embodying my invention, but it is to be understood that I do not limit myself 2 to such form since the invention, as set forth in the claim, may be embodied in a plurality of forms. 7

In the drawings; Fi 1 shows in perspective the paper filing punch of my inventio Fig. 2 is a cross section of the punch of my invention, the plane of section being indicated by line 22of Fig. 1.

Fig. 3 shows in perspective a portion of a bundle of papers perforated with my punch. 'The paper filing'punch of my invention preferably comprises a plane base having upstanding walls thereon for positioning a sheet of paper, together with means on the base forperforating the paper when it is positioned against the walls.

In the preferred form of my invention dis closed in the drawings, a sheet of material 6, preferably aluminum or a comparable light metal, isprovided with a pair of upstanding walls 7 and 8 respectively. The base 6 is usually substantially square so that all of its corners are rectangular but for convenience, one corner can be cut to form the side 9. Diagonally opposite side 9, the base is preferably of rectangular contour andthe dihedral angle included between walls 7 and 8 is then a right angle. The walls are usually of grad- 1927.

uated height, being highest at their meeting edges and gradually din'iinishingtoward the corners of the base. They can be joined at j 1 their meeting edges by solder or other joining means if desired, or they can simply be bent.

into position to remain by theirown rigidity. Ina predetermined position with respect ,to the walls 7 and 8, aprong 11 is provided.

The prong can either be cut from the material. of the base 6 and turned up to lie substancated with the plane of the prong substantially b-isecting the dihedral angle between the walls 7 and 8. The edges of the prong are sharpened to facilitate the perforation of paper. A sheet of felt 12 or similar material base 6 to revent the metal from marring finished sur aces. Nearer the side 9, the base 1s pierced by a perforation 13 which extends .thru the felt 12 also and affords a convenient means for hanging thepunch.

To use thepunch, the user grasps the base i 6, usuallyin his left hand, and taking a sheet of paper in his other hand, positions it with is preferably secured to the bottom of the its adjacent rectangular edges against the I walls 7 and 8. He then presses down onthe paper, at the same time keeping it in contact with the walls, and forces it over the upstanding prong 11. The paper is thus perforated with'an aperture situated at an angle to the rectangular sides and located at a predetermined distance therefrom. The sheet of paper can be Withdrawn fr mtl1e filing punch or it can be left in place and other sheetsof paper superposed in the same manner. When a number of'sheets of paper have been perforated, they are removed as a unit from the filingpunch. and a staple or fastener 14, as shown in Fig. 3, is inserted thru the alined perforations and securely retains the sheets in their neatlyregistered position.

It will be appreciated that I have described a paper'filing punch which conven'ientlycan be heldin the hand of the user and which provides a way for perforating papers neatly and accurately so that they can be secured together ina uniform, tidyway.

I claim:

A paper filing punch comprising a flat an gular sheet metal base having two adjacent base, said base being cut away to provide a edges upwardly bent to form sides perpen, straight edge portion transversely between dicular to each other and to the base defining the sides. 10 a dihedral surface, a single piercing element In testimony whereof, I have hereunto set connected With the base and vertically dismy hand.

posed in a plane which bisects the angle formed by the upwardly bent portions of the GUY A. SHADDUCK.
